B2B Sales Expert (Train AI Models Part Time!)

Role Overview

Mercor is partnering with a leading AI research organization to engage experienced B2B sales professionals for a project focused on evaluating how well AI systems perform real-world sales work. Rather than producing deliverables yourself, you will define what excellent work looks like: designing task-specific grading criteria and scoring completed work samples with rigorous, well-reasoned written justifications.

Responsibilities

• Design precise, task-specific grading criteria for real-world sales deliverables (prospecting sequences and outreach emails, discovery and demo call plans, account and territory plans, proposals, mutual action plans, forecast and pipeline reviews)
• Score AI-generated and human work samples against those criteria, with detailed written justifications for every score
• Apply consistent, evidence-based judgment so that scores are reproducible and defensible
• Incorporate structured feedback from senior reviewers and iterate quickly on your work

Qualifications

• 5+ years of professional B2B sales experience, including quota-carrying roles
• Background as an Account Executive or Sales Development Representative selling into large enterprises
• Deep fluency in the day-to-day craft: outbound prospecting and sequencing, discovery and qualification, multi-stakeholder deal management, pipeline hygiene and forecasting, and structured sales methodologies
• Exceptionally strong written communication, with the ability to explain exactly why a piece of work would or would not land with a real buyer
• Detail-oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers
• Prior experience with AI training, evaluation, or human-data projects is a strong plus
